House prices rise at fastest rate for14 months The cost of a home in China rose sharply in October,with the price surging up at its fastest rate for 14 months. According to the National Bureau of Statistics(NBS),property prices in 70 Chinese mainland cities rose by an average of 3.9 percent when compared to their price last October. Prices of homes in new residential buildings went up 4 percent on average in October year-on-year, while the cost of State-subsidized housing edged up by 0.6 *** of commercial residences climbed 4.4 percent and high-end housing went up by 1.5 percent.

Economists warn of housing bubbles World Bank economists warned on January 25 about the risks of asset bubbles in China even as the government tries to hold back excessive lending and keep prices stable. Asset price inflation,or increases in housing prices in particular, is potentially"very dangerous"for China because they are selfreinforcing, made possible by"very cheap credit",said Hans Tim-

Journal of University of Science and Technology Beijing 2007年第1期14卷 85-88页

作者： Guangyao Jia Zhimeng Guo Materials Science and Engineering School University of Science and Technology Beijing Beijing 100083 China

Silica fibers-reinforced, fused silica composites were fabricated with repeated vacuum-assisted liquid-phase infiltration. The mechanical properties, thermal properties, and ablative properties of the samples were evaluated. The effect of the silica fiber content and treatment temperature on the flexural strength of the three-dimensional SiO2 （3-D SiO2） composites also was investigated. The SiO2 composites show good mechanical properties and excellent ablative performance. The flexural strength increases with an increase in silica fiber content, and decreases with an increase in treatment temperature. When the volume fraction of the silica fiber is 50vo1% and the treatment temperature is 700℃ the flexural strength of the composites reaches a maximum value of 78 MPa. By adding cyclohexanone surfactant, the infiltration property can be largely improved, resulting in the density of SiO2 composites increasing up to 1.65 g/cm^3. The fracture surfaces of the flexural specimens observed using SEM, show that the pseudoplasticity and the toughening mechanisms of the composites are caused by absorption of a lot of energy by interface debonding and fiber pulling out.
